Abstract

Production of alkoxysilanes having a low acid chloride content comprises reaction of a chlorosilane and alcohol, removal of hydrogen chloride and addition of a metal alcoholate and distillation at reduced pressure. A process for the production of alkoxy silanes (I) that have a low or zero acid chloride content comprises: (A) reaction of a chlorosilane with an alcohol in a water- and solvent free phase with removal of the byproduct hydrogen chloride from the product mixture; (B) transfer of the resulting product mixture to the sump of a distillation unit with addition of a metal alcoholate at 10-60 degrees C in an at least equimolar quantity with respect to the acid chloride; and (C) distillation of the treated product mixture at reduced pressure.
